STOVE-OVEN LlNING.

SPECIFICATION forming part of Letters Patent No. 232,950, dated October 5. 1880,

Application filed February 18, 1880.

To all whom it may concern Be it known that I, DAVID A. DioKINsoN, of the city of Baltimore and State of Maryland, have invented a new and useful Improvement in Stove-Oven Linings, of which the following is a specification.

My invention relates to an improvement in linings for ovens of cook-stoves and ranges.

Soapstone possesses the property ot' retaining heat for a greater length ottime than most other mineral substances, and for this reason it is Well adapted for certain uses in connection with domestic cookery. 4

I am aware that soapstone has been employed in the manufacture of stoves, and that the bottom, the top, and each vertical end ot' the oven has been constructed ot an open rectangular iron frame, with a soapstone or steatite panel' ixed in the opening of such frame, and that recently it has been applied as a lining for stove-oven doors, the object in the latter use being to prevent the loss of heat by radiation from the exposed doors, which, Without a lining, are very thin. This particular application of soapstone, however, does not eii'ect the object which I have in view-to Wit, to prevent overheating ot' the oven at the top and bottom, and thus avoid the burning of articles ot'food, and at the same time to maintain Within the oven an even temperature, not so liable to be affected by opening the ovendoors, which is frequently necessary.

My invention has particular reference to a soapstone lining on the inside of the oven to cover the top and bottom plates thereof, and Will irst be described, and then designated in the claim.

Figure l is a side elevation of a cook-stove embodying my improvement. Fig. 2 is a transverse section through the oven. Fig. 3 is a perspective view ot' the soapstonesustaining frame.

The letter A designates the top iron plate intervening between the flue and oven, and G the bottom iron plate of the oven, of an ordinary cook-stove or range. If the fire should be such as'to unduly heat these plates the result would be to burn any article of food that might be in the oven. I therefore providea slab of soapstone, B, as a lining on the inside of the oven for the top iron plate, and sustain the same in position against the said plate by means of a metal frame, (shown iu Fig. 3.) In practice this frame consists of strap or band iron bent in such form as to lit Within the oven, with the ends e resting either on the bottom of the oven or on the ordinary projecting bead g on the side Walls, which sustains the shelf'. These ends constitute the legs of the frame, and at that. part of the two bands which extends across the oven-top bars j' may be secured, so as to connect the several parts. Thus constructed the trame is adapted to sustain the stone slab in its position, and said frame is no obstacle or hinderance to the use ot' the oven.

It is obvious, however, that a suitable sustainillg-i'ranie might be made in manner differ@ ent from that herein described, and myinvention, therefore, is not limited thereto. Also, in 'manufacturing new stoves a suitable bead similar to bead g could be cast integral with the front and rear plates to support the top slab.

A similar slab ofsoapstone (designated by the letter D) is placed within the oven on the bottoni plate, and the above-named tivo slabs serve to prevent the burning ot' articles of food, and as retainers ot' heat theylprevent any perceptible lowering ofthe temperature Within the oven, which, ordinarily, Without them, the opening ofthe door occasions.

My improvement herein claimed constitutes an attachment which is applicable to any stove or range, no alteration in the castings of the latter being necessary.

Having described my invention, I claim and desire to secure by Letters Patent of the United States* In a stove-oven, the combination, With the ordinary top iron plate which intervenes between the tlue andoven,of a stone slab against the said plate on the inside of the oven, and means, substantially as described, to sustain the slab, as set forth.

In Witness whereof I hereunto set my hand.

DAVID A. DICKINSON.
